Superseded by larger layout refactoring proposal (“moose”). Part of the refactoring work could still be relevant/applicable in isolation and has been broken out into specific design documents; unrooted layout, removing deprecated paint layer.

Abandoned due to the high implementation complexity, high maintenance costs and relatively low level of enthusiasms from prospective clients. Does not necessarily make sense in isolation and should be considered as a part of a bigger layout refactoring or work to support custom layout. Most prospective use cases can be satisfied with a text metrics API.

We unblocked all existing blockers. The metric is stalled for other problems, and one topic is still under discussions, but Blink is no longer the blocker at this point and the failure to meet the goal is outside the control of the blink team.
